Editor note: Here is a nice little review one of the first BBSHD customers wrote on the new Bafang BBSHD which is on Cyber Monday sale at Lunacycle.com

So I just installed my new BBSHD in place of my BBS02. It went into my 68mm BB bike, the 02 was standard and the HD was for a 68mm BB. The HD seems better in every way. It’s a lot bigger, the cranks are centered on the frame (02 was 1/2 in to the right) and the gear cover is metal with a nice seal (02 was crap in this respect). Also, the chain line is better.
With the stock 46T sprocket, chain was straight in 5th gear of my 9 spd (42T Luna Bling Ring was ordered with the kit but they aren’t quite done yet and the 02 Lekkie doesn’t fit). The install of this kit is super simple, anyone can do it. It’s plug and play but if you want to change settings on the controller the same cable and software that worked to change settings on the 02 works with the HD. It came from Luna set for throttle in PAS 0 they way I like but they had Max amps at 25 (this was just an over sight, all HD’s from Luna come set to 30A) . I tried it like that then bumped it up to 30A (controller won’t accept any higher number) .
I also tried setting throttle mode to speed and to lie about the wheel size. It does have a little more power but throttle isn’t smooth enough for balance point wheelies so I put it back. Just got back from my first real ride and loved it! Only a little more power, as you would expect for a 5 amp increase, but I could ride this thing differently from the 02. I always ride in PAS 0 for throttle only and only ride on single track trials. After reading about the controller problems of the 02 (mine did not have the newer 3077 FETS) I would shift a lot to make sure I always had a fast cadence. With the HD I shifted much less and could stay in a gear from a slow cadence till I couldn’t pedal fast enough and it was still pulling.
I think less shifting is going help the drive train last. Now, where I ride it doesn’t have any real long hills and today was about 50F but no matter what I did the motor and controller were not even warm! The chain did fall off twice when not under power and going over a bunch of small roots, I hope the narrow wide Bling Ring fixes that. Also, this thing can clearly take more power, I really want to give it 10 more Amps! It would be nice to do it without an external controller. I know someone will unlock this thing soon!
